I believe that the commercial mortgage/real-estate market still has a ways to go on the downside, and is much earlier in its trajectory than the residential market (as I'm sure you'll agree judging by some of your posts on the subject). Lehman's residential and commercial mortgage exposures are roughly equivalent ($37.3 vs $38.9 billion as of 11/30/07).
I also believe that even on a gross basis, Lehman has not taken large enough write-down in comparison to other companies. I believe they have accomplished this by moving mortgage assets to Level 3. I've loved reading your blog and truly appreciate the unique and in-depth analysis performed on target companies thus far."
